Focusing distance is roughly 40 meters (131ft). The resulting depth of field is nearly 5 meters (16ft) even at f2. The 16:9 ratio might give an illusion that this was taken much closer. However, I would have probably had to go swimming in order to close the gap .
was the photo taken with a DX sensor? That's a huge distance from your couple just to put their entire bodies in the frame..
This will quickly turn out to mess up the thread so I will write an explanation which hopefully won't leave any confusion.
Most of the questions would be answered just by clicking the link under the picture where for example a short explanation can be read about the taking of the picture. This is by no means a posed picture (for me) and I just took it while strolling around the park when I spotted these people. Therefore, the picture is taken where I happened to be at the time and this was across the water which put me several tens of meters away. The exif data, which can be read after clicking the link under the picture and then (i) for info, should have all the necessary information (D700, 200 mm, f2.0, 1/800, ISO 200 etc.) except for the focus distance which is not saved by photoshop CC (for example CS5.1 still saved this info). However, the exif of the raw image says that the focus distance recorded by the camera for this picture is 39.81 meters. If we calculate the subject distance based on the focal length (200 mm), the vertical height at the subject location (in the original 3:2 image the vertical height where the people are standing is 4.34 meters if we assume the man is around 170 cm tall. ), and the height of the D700 sensor (23.9 mm) we arrive at a value of 35.76 meters which is quite close to the value in the exif data and of course includes some error because I just estimated the vertical height. http://blog.buberel.org/camera-lens-calculators.html
As a reply to the next post:
The D800 and D700 sensors are both FX format so the size is almost identical (23.9 mm is the height and 36 mm is the width of the sensor in the D700). I actually have both but I like to use the 200 mm on the D700 and a shorter focal length on the d800e as I usually use both bodies and don't need the extra resolution with the 200.
thanks for the info. I think the difference i've seen is due to the greater magnification from the physical size of the d800 sensor + the 200 f2 vs. the much smaller D700 sensor.
I like this scene.. it's always nice to see something different from across the world.

Picked up a LNIB 200/2 ais from adorama... Here's a test shot. Think I'm going to like this lens. It pairs beautifully with the Sony A7r btw..
